It would be real nice to be able to only show Star'ed items on the watch. Currently it just shows the HotList, and when I am out an about focused on certain items, it would be nice to star those items and just have that list on my watch.

Excited to see this! I just switched back to ToodleDo after not using it for many years - I forgot how awesome the HotList is. However...I now have an Apple Watch and need that to be my primary task intake method (using Siri).
